ECU Remapping & Car Tuning is what we do, and what we do well. For everyone at BHP UK, car remapping, engine chip tuning, remapping motorbikes, trucks (and even tractors!), isn’t just our business, it’s our obsession. However, we do understand that not everyone can be a genius like ‘all’ the staff are at BHP UK and we also understand that there are always going to be questions which you might need to ask… This is why our boys (and girls) have come up with a list of the most commonly asked questions that they get asked (and are sick of answering!). If you still have a question that you need answering, then please do not hesitate to get in touch. And we would love to answer any question or query you may have.

Q: What is an ECU?

A: An engine control unit (ECU), is also known as a PCM (powertrain control module). This is an electronic control unit, which controls actuators on an internal combustion engine to help the engine run at optimum.

Q: What is ECU Remapping?

A: ECU remapping is a tuning procedure of the engine, that allows several manufacturer constraints to be lifted from the vehicle. Sound confusing, click here for more information on what ecu remapping is & why these limitations are placed by vehicle manufacturers.

Q: If my car can be improved so much by an ECU Remap, why hasn’t the factory done this?

A: This is a very common question that we get asked. The answer is very simple, the factory could have remapped your car, however they choose not to for many reasons, the most important is marketing. Cars are manufactured to fit into a market category and there is certain criteria for make & model categories and the car’s ECU is mapped to fit into these categories. It also allows for a enough power separation between various models. Manufacturers will also produce two identical cars with identical engines, then simply offer the car in two states of tune, this is a very economical way of extending a model range. Examples of such cars include the BMW Mini One and the BMW Mini Cooper, another example is the VW Golf TDi 104BHP and the VW Golf TDi 140bhp.

A: On most cars the brakes can easily handle the extra power. However, should you want to upgrade your brakes we can advise & supply upgraded pads, discs and calipers.

Q: What makes and models can you remap?

A: We remap all makes and models. If you can’t find the car make or car model you are looking for, please don’t be disheartened. Give us a call and we will definitely be able to find you a solution for your car.

My Alfa Romeo 159 immediately felt more lively and definitely more responsive with much more mid-range power. Average mpg used to be 42mpg and is now 51mpg... So much happier with my fuel bills now! Impressive stuff!

Andrew Scholes

I want to say a big thankyou to the remapping team here for their expert Engine Tuning and for ECU Remapping my BMW 520d last week. The only disadvantage is that I'm driving like a teenager again with all the extra bhp and torque! I know I'll see the benefits in fuel economy and increased MPG, when I start driving normally...Thanks again!

Richard Blakeley

Originally met these guys at The Autosport Exhibition @ The NEC. Was thrilled to find out they were quite local to me. Can’t say enough how impressed I am at the success of the remap to my Audi A4 170bhp. The difference is phenomenal… sooooo smooth and the power comes so quick low down.

Bradley Pates

Since you re-mapped my VW Passat it’s just like driving a different car, the power is amazing and the performance as a whole is second to none. Every time I accelerate it's like pressing a warp drive pedal. And I’ve also noticed the MPG has gone up considerably. Great Performance Remapping.
